The LSI SAS 9400-8i tri-mode storage adapter is ideal for high-end servers utilizing internal storage or connecting to large-scale external storage enclosures. It has the ability to operate NVMe, SAS, or SATA storage devices in a single drive bay*, giving you maximum flexibility in server system design. With up to eight internal ports, the adapter can connect up to 1024 SAS/SATA devices or 24** NVMe devices, providing superior scalability. It is based on the SAS3408 IO controller and features the latest x8 lane PCI Express 3.1 connectivity, delivering increased connectivity and maximum performance needed by critical applications. Plus, the low-profile adapter seamlessly fits into any small form factor.

Industry's First HBA with Tri-Mode SerDes Technology

Broadcom enables high performance storage connectivity and flexible system designs that support any combination of NVMe, SAS and SATA devices with the industry’s first HBA with Tri-Mode SerDes. The Tri-Mode HBAs expand Broadcom’s industry leading family of 12Gbps SAS HBAs with 8 and 16 port internal, external and combination Tri-Mode port options.

Note: The LSI SAS 9400-8i features eight internal ports.

NVMe Performance Gains for Storage

The Tri-Mode Storage HBAs bring NVMe performance benefits to the storage tier by providing connectivity and data protection that HBAs have offered for over 20 years for SAS/SATA interfaces.

Based on the single core SAS3408 Tri-Mode Storage I/O controller (IOC), the LSI SAS 9400-8i increases bandwidth and IOPS performance compared with the previous generation. It provides up to 12Gbps SAS and up to 6Gbps SATA performance across eight lanes of PCIe 3.1 connectivity. In addition, it’s backwards compatible with previous SAS and PCIe generations, providing SAS data transfer rates of 6Gbps and 3Gbps per lane, and SATA data transfer rates of 3Gbps per lane.

Endless Design Flexibility Using Tri-Mode Controllers

Broadcom Tri-Mode SerDes Technology enables the operation of NVMe, SAS, or SATA storage devices in a single drive bay*. A single controller can operate in all three modes concurrently servicing NVMe, SAS, or SATA drives. The controller negotiates between the speeds and protocols to seamlessly work with any of the three types of storage devices. TriMode support provides a non-disruptive way to evolve existing data center infrastructure. By upgrading to a Tri-Mode HBA, users can expand beyond SAS/SATA and use NVMe without major changes to other system configurations.
